Aquatic Invasive Species (AIS) are non-native species (also referred to as exotic, alien, or non-indigenous) that cause harm to the environment, the economy, or human health. Lake Champlain is home to 51 known aquatic invasive species (AIS). Many more are “on the doorstep” of Lake Champlain, threatening to enter from nearby waterways. Once introduced to Lake Champlain, AIS have the potential to infest other inland water bodies in the Basin, which is why spread prevention is critical.
